rhesus monkey, on Silver Spring. the monkeys, apparently, were brought from Cambodia by a tourist-trap developer in the early 1900's.
he'd intended an island in the spring to be their home, not knowing that Cambodian monkeys can swim. now they roam Florida, though I have yet to see them anywhere else.
we learned that from overhearing the tour guides speaking from glass-bottomed tourist vessels at the headwaters of the spring.
